LEE S. CHAD'WICK, 015 EAST CLEVELAND, *OHTO, ASSIGNOR TO THE CLEVELANDFOUN- JURY COMPANY, 01E CLEVELAND, OHIO, A CORPORATION OF OHIO.

LIF'IING DEVICE FOR COMBUSTION-TUBES.

To all whom it may concern Be it known that 1, LEE S. GHAnw1cK,,a

citizen of the United States, residing at East lltll Cleveland, in thecounty of'Cuyahoga and State of Ohio, have invented a certain new anduseful Improvement in Lifting Devices for-(lombustion-Tubes, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings.

This invention relates generally to oil or vapor burners and moreparticularly to the means for raisin and lowering the combustion orcomming ing tubes employed in connection with the wick or burner proper.

Une object ofthe invention is to provide a simple and efiicient m answhereby the combustion or commingling tubes can be quickly and easilyraised and supported away from the wick, so that the burner can belighted.

Another object of the invention is to pro-.

vide means for properly positioning the combustion. tubes upon the wicktube after the burner has been li hted.

A still further 0 j ect of the invention is to provide a simple andeflicient means for raising and lowering the combustion or comminglingtubes which can be used in connection with any type of wick stop withoutinterfering in the least with said stop.

With these and certain objects in view, the

invention consists in thenovel features of .construction and combinationhereln after fully described and pointed out in the claims.

Inthe drawings forming a part of this specification, Figure 1 is acentral vertical section through an oil burner provided with my improvedmeans for raising and lower ing the combustion, or commingling tubes,said tubes being shown in their lowered or normal position; Fig. 2 is asimilar view showing the tubes raised to permit the lighting 'of thewick; and Fig. 3 is a detail perspective view illustrating the lockingmeans. In carrying out my invention I provide a wick'holder 10comprising the inner and outer Wick tubes whlch are united at theirlower ends as usual, and near their upper ends are constructed with theinner and outer annular ledges 11 and 12, respectively,

. upon which rest the inner and outer combus Speciflca'tionof LettersPatent.

rying a central thimble 19 which is boredv centrally to receive theupper end of the lifter rod 20, said rod extending downwardly throughthe ring-like wick stop 21, and through an elongated slot 22, producedin a strap 23 arranged within the inner Wick tube near the lower endthereof, one end of said strap being secured to the inner wick tube asshown, while the other end of said strap is projected downwardly belowthe lower end of wick tube as shown at 2-1. This downwardly projecting.end may be somewhat broader than the strap, and is longitudinallyslotted from the end of wick tube. downwardly as shown at 25, the upperend of the slot having the lateral notches 26, which are adapted toreceive theribs or fins 27, swaged upon the outwardly projecting portion28 of the lifter rod 20, said rod, after passing through the slot 22being bent at 29 to accommodate the oil pipe, (not shown) and is thenbent at 30 so as to project the free end thereof through the slot 25,the extreme end of the lifter rod being curved as indicated to provide asuitable handle. By means of this rod constructed as herein shown anddescribed and connected to the commingling or combustion tubes by thecentral thimble and perforated diaphragm, I am able to raise and lowerthe commingling or combustion tubes at will, by simply raising andlowering the lifting rod, and it Will be noted that when the rod isgrasped at its lower end, and lifted for the purpose of raising thecommingling or combustion tubes clear of the burner, the said tubes willtilt slightly to one side as shown, inasmuch as the lifting rod ispermitted to rock rearwardly on account of the slot 22 in the strap 23,and this tilting motion of the commin lin tubes rovides a reater s aceat b O Patented J an. 116, 191V.

or uppermost position, maintaining the commfngling or combustion tubeselevated until the lighting operation has been accomplished. Then bypushing the handle inwardly to disengage the finsor ribs, the rod 20 canbe lowered and these'fins or ribs engaging the rear face of thedepending ortion 24 insures the commingling or com ustion tubes to beproperly seated upon the supporting ledges of the wick tubes.

It will be understood that the wick stop can be of any desiredconstruction and it can be omitted entirely as the tube raising meanshere shown is entirely independent of any wick stop construction.

It will thus be seen that I provide a cheap, simple and eflicient meansfor raising, lowering and positioning the combustion tubes withreference to the burner.

Having thus described -my invention, what I claim is 1. The combinationwith a burner and combustion tubes, of a lifting rod connected at itsupper end with said tubes, said rod having a vertical and lateraltilting movement, and means attached to said burner for supporting saidrod in its raised and shifted position. i

2. The combination. with a burner and combustion tubes, of a lifting rodconnected at its upper end with said tubes, a guide for said rod withinsaid burner, said guide being slotted to permit a limited lateralmovement of said rod and means attached to said burner for supportingsaid rod in its raised and shifted position.

3. The combination with a burner and combustion tubes, of a lifting rodconnected at its upper end with said tubes, said rod having a verticaland lateral tilting movement, the lower end of said rod being projectedoutwardly beyond the burner, and means attached to said burner forguiding the vertical and outwardly-projected porrod, said rod having avertical and laterally tilting movement, the outwardly projectingportion of said rod and that portion of the guiding means cooperatingtherewith being shaped to hold said rod in its elevated and tiltedposition.

5. The combination with a burner and combustion tubes, of a perforateddiaphragm attached to the inner combustion tube, a thimble carried bysaid diaphragm, anda lifting rod extending upwardly through the burnerand having its upper end fitted in said thimble, a slotted guide carriedby said burner whereby said rod has a vertical and lateral movement andmeans carried by the burner for locking the lower end of said liftingrod in its raised and shifted position.

6. The combination with a burner and combustion tubes, of a rod havingits upper end connected with said tubes, the lower end of said rod beingprojected outwardly beyond the burner, and a guide attached to saidburner and adapted to guide the vertical and outwardly projectedportions of said rod, the outwardly projected portion of 'said rod beingprovided with means for engaging a portion of said guide whereby the rodis caused to travel vertically until it reaches the limit of itselevation.

7. The combination with a burner and combustion tubes, of a guideattached to said burner and comprising a horizontal and a vertical,portion, said portions being slotted, the upper portion of the verticalslot being enlarged, and a lifting rod comprising a vertical and ahorizontal portion, the upper end of the vertical portion beingconnected with the combustion tubes, the horizontal portion havingenlargements adapted to engage the vertical guiding portion as setforth.

8. The combination with a burner and combustion tubes, of a rodcomprising a vertical and a horizontal portion, the upper end of thevertical portion being connected with the combustion tubes, a guideattached to the burner, said guide comprising a horizontal portion and adepending vertical portion, the horizontal portion having a centrallyelongated slot, the vertical depending portion being slottedlongitudinally, the upper portion of said slot being enlarged, thehorizontal portion of said lifting rod being enlarged and adapted toengage the depending slotted portion of the guide as set forth.

9. The combination, with a burner and lifting member, of a lifting rodconnecting at its upper end with said lifting member, said rod having avertical and lateral movement and means operatively controlled by saidlateral movement of said lifting rod for holding said lifting member inthe raised position.

In testimony whereof, I hereunto affix my signature.
